Skinner's Brewery has teamed up with the Cornish Mining World Heritage Site to donate 1p from the sale of every pint of its best-selling Cornish Knocker ale on draught.
The money will go towards protecting and preserving the Cornish Mining World Heritage Site via its Discover the Extraordinary project.
Cornish Knocker is named after the elfin spirits from Cornish folklore who lived down the mines.
They would guide the miners to the rich veins of copper and tin, whilst warning them of impending disasters with their "knocking".
It is said that Cornish miners would throw crusts from their pasties into the mine to keep on the right side of the Knockers.
The partnership will be made official at Kernow Fest at Heartlands, a gateway to the Cornish Mining World Heritage Site, on Sunday (May 26).
Silvia Lowe, principal officer of the Discover the Extraordinary project, said: "After a hard day of work down the mine, Cornish men would welcome relaxation with a pint of local ale at their local pub.
"Working with a local brewery is another way to continue to tell these stories of our mining heritage in an exciting and contemporary way.
"We are thrilled to be working with Skinner's Brewery and with their help and the support of those who love Cornish Knocker, we will be able to continue to protect our precious mining landscape which is of global significance."
Steve Skinner, chief executive of Skinner's Brewery, said: "Cornish heritage is extremely important to me, so I am delighted to be able to support it through my business.
"The knockers were the protectors of the miners and our customers can now protect our mining landscape.
"Lovers of our Cornish Knocker can enjoy their pint down the pub knowing that every one that is consumed will be raising funds to preserve Cornish mining heritage for future generations to enjoy."
Donations to the Cornish Mining World Heritage site will also come from sales of casks of Cornish Knocker.
